I'm very much approaching this from a level of "I know what some of those words mean", but is this result surprising that quantum systems lose entanglement at high temperatures? Isn't that the whole point of running quantum computers at very low temperatures?
- tux3 2y agoRegistering my uneducated guess: Is this implying there was previously hope you could trap a hot system in a Gibbs state and demonstrate nice stable quantum supremacy with those, but they found hot Gibbs states are necessarily all boring and decohered after all?
- hughesjj 2y agoI believe so, from abstract > A priori the task of preparing a Gibbs state is a natural candidate for achieving super-polynomial quantum speedups, but our results rule out this possibility above a fixed constant temperature.
